Vegetables. Most veggies are OK for dogs, either raw or cooked.  Rice and pasta are good too.  Our dog eats rice everday as part of her diet.  Cooked meat in small amounts (in moderation).  Our little dog gets boiled chicken daily too.  She's old and a vet recommended it.  It's helped as she had some serious problems with canned dog food.  Some dairy products are fine (low fat) but again, in moderation. 

And many dogs love fresh fruits such as apples, berries, bananas, and seedless watermelon.   Once again, moderation is the key.
